IMPROVEMENT IN RAILWAY FREIGHT-CARS.

Specication forming part of Letters Patent No. 135,717, dated Februaryl1, 1873.

To all whom it may concern:

Be it known that I, BENJAMIN P. LAMA- soN, of Milton, in the county ofNorthumberland, in the State of Pennsylvania, have invented a new andImproved Mode of Gonstructing Steam Railroad Gars for Transporting Grainand Merchandise; and I do hereby declare that the following is a full,clear, and

exact description thereof, reference being had to the accompanyingdrawing and to the letters of reference marked thereon, in which- Figurel is a side elevation 5 Fig. 2, a longitudinal sectional elevation Fig.3, a transverse sectional elevation 5 and Fig. 4, an end elevation.

My invention relates to an improved freightcar, composed of an outershell of plate-iron, of oval form, and lined inside with wood, a

space being left between the two for absorp-A tion of heatand providedwith suitable doors and apertures for loading and unloading, the bodythus made being secured upon a frame or truck composed of bolsters,sills, transoms, and stringers, by metal straps, all con- Astructed andarranged as hereinafter shown and specified.

To enable others skilled in the art-to make and use my invention, I willproceed to describe its construction and operation.

I construct a tube of iron, of the desired capacity and oval in form, asseen at A A, Figs. l and 4. This'tube I line throughout the inside withwood or its equivalent, (seen at a a, Figs. 2 and 3.) Between the ironshell c of the frame and the wooden lining a a space, d, is provided.This space is designed to absorb heat, and may be filled with a suitablepacking or allowed to remain open. The wooden lining a inside of theframe is secured by means of wooden rings fitted to the inside The bodyis provided with two outside doors, B, one at either end and on oppositesides. There are also two inside or grain doors, O, in the rear of theoutside doors. These inner doors are designed for closing up theapertures when cars are laden with bulk grain. All these doors are madeof iron, and

in practice will be provided with friction-rollers running inproperly-constructed guides secured to the body. The body is alsoprovided with a manhole, e, and apertnresff, one at end sills F. Theseend sills F extend the full width of the frame, as seen at F, Fig. 4.The body-holsters Gr and transoms H extend. full width of frame and upbetween the two stringers E equal to their height. That portion of thetransoms and bolsters extending up between the strin gers is shaped toconform to the lower part of body A, as shown in Fig. 3, and in whichsaid cylinder rests when placed on the frame.

To avoid accidents the frame is provided with a railing, I, supportedvby posts J secured to the sills D. That portion of the railing in frontof the doors B is movable, and can be removed, when desired, to admitlading into the car. Iron stays k are firmly secured to theframe, andare of suflicient length to bear upon the car-floor Z at the'same timethe frame rests in the cradle formed in Ithe transoms. The stays 7c aredesigned to aid in keeping the cylinder in position, while the ironstraps m, which pass over and around the body down through the frame,secure the body firmly to it.

The outside doors B answer the ordinary purpose of car-doors, and areoperated forward or backward by the hand, as desired. When closed theyare secured by a hasp and staple.

The inside doors C are designed exclusively for grain or freight of likenature when transported in bulk, and are operated inlike manner as theoutside doors. .y

The wickets h are designed to facilitate the discharge of grain. Bymeans of these wickets the difculty and necessity of opening the largeinside door are entirely obviated.

The vent g immediately in the center on the under side of the cylinderis designed also for the discharge of grain. The man-hole e is anopening through which the body is filled.

The port-holes f in the ends of the cylinder are designed fortheaccommodation of long material that cannotenter through the side doors.v

Having thus described the construction and operation of my invention,what I claim as wickets' h, when eonstrueted and arranged as new, anddesire to secure by Letters Patent, described, and combined with atruck, in the is manner and for the purpose set forth.
